After
reviewing the findings from 18 different studies on soy and breast
cancer, researchers from John Hopkins University and Georgetown
University found women who consume soy foods have a lower incidence of
breast cancer. According to findings,
there was an overall 14 percent lower risk in women who consumed soy.
However, researchers could not be sure that these benefits were from
the soy or the fact that those women eating soy possessed better health
habits. These studies focused on soy-based foods such as tofu
and soymilk and not soy supplements. It should be noted that soy
supplements can have very different biological effects as compared with
soy-based foods. The researchers also cautioned against supplementing
with high doses of soy, especially those women are breast cancer
survivors or those women at increased risk for breast cancer.
